The invention relates to improvements in cream-separators.

The object of the present invention is to improve the construction ofcream-separators and to provide a simple, inexpensive, and eficientdevice designed to receive milk as soon as it comes from the cow andcapable of aerating and purifying the same and of separating the creamfrom the milk.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure l is a perspective view of a cream-separator.Fig. 2 is a vertical sectional view of the same. Fig. 3 is a detailperspective view of the spreader.

Like numerals of reference indicate corresponding parts in all thefigures 0f the drawings. Y

1 designates a cylindrical receptacle designed to receive a supply ofcold water for lowering its temperature to chill the milk' as it isdelivered into the device and remove the impurities of the same andseparate the cream from the milk. The receptacle is provided with a capor cover 2, composed of inner and outer inclined walls 3 and 4:, unitedat the top of the cap or cover, as clearly illustrated in Fig. 2 of theaccompanying drawings. The outer wall 4, which inclines upward andinward to form a tapering trunco-conical track, is provided withperforations 5 and has a horizontal supporting-flange 6 and a dependingflange 7, which extends into the receptacle, wherebythe cap or cover issecurely held thereon. The inner and outer oppositely-inclined walls 3and 4 are disposed in substantially the same horizontal plane, and theirupper and lower edges are arranged in substantially the same planes. Theinner wall 3, which is imperforate, inclines downward and inward andforms a funnel and is provided with adepending cylindrical portion oriiange strainer 9 detachably secured to it, whereby the milk is strainedas it is poured into the device, as hereinafter explained. The innerimperforate wall, which forms a funnel, extends downward to a pointbelow the imperforate portion of the outer wall of the cap or cover, andit forms a deflector and is adapted to throw gasesand impurities outwardt-oward the perforations should such gases iinpinge against it in theirascent to the top of the device. The strainer may be mounted on thedepending fiange or portion S by any suitable means, and it ispreferably readily removable in order that it may be cleaned after use.

The receptacle is provided with upper and lower transparent panels l0and ll, forming gages and adapted to enable the operator to inspectreadily the contents of the device.

The receptacle is supplied with a sufficient quantity of cold waterbefore the milk is poured into it, the cold water being preferably equalin bulk to the milk to be separated. The milk is poured into the cap orcover, which forms a funnel to direct the same to the center of thereceptacle, and the milk entering the receptacle contacts with a conicalcorrugated separator l2, adapted to divide the milk into iine spray orsheets, whereby the yvarin milk will be thoroughly subjected to the coldair and will be aerated and purified, the gases passing upward andoutward through the perforations 5. The perforations 5 are formed in thelower portion of the outer Wall of the cap or cover, the upper portionof the outer wall being imperforate to form a shield. This will preventthe gases and impurities passing outward through the perforations fromcoming in contact with the milk as it is poured into the device. If theperforations were extended to the extreme upper edge.of the outer wall,the gases issuing at the top of the device around the central funnelportion might aiiiect the milk as it is poured into the separator.

The conical corrugated spreader 12 is mounted on a stem or support 13and is located centrally of the cap a short distance below the strainer9, so that the mil-k will be thrown outward in all directions. The stemor support 13 preferably consists of a tube or rod,

suitably secured to the bottom of the recep- After the milk is pouredinto the device it is permitted to remain therein from sixty to ninetyminutes, which time is amply sufiicient to cause the cream to rise tothe surface of the liquid. The diluted sweet milk, which has beenseparated from the cream, is drawn off at the bottom of the receptaclethrough a spigot 14 or other suitable means,

and by watching the cream-line through the transparent portions of thereceptacle the operator may readily ascertain when the diluted milkhasbeendrawn off. The cream is then removed and the operation iscompleted.

It will be seen that the cream-separator is exceedingly simple andinexpensive in construction, that itis easily operated, and that themilk as it is poured into the separator breaks and spreads in linesheets to contact perforated portion of the outer Wall, and theperforations terminate short of the top of the outer Wall to provide animperforate upper portion, so that the gases and odors given off by themilk will not escape directly at the point Where the milk is poured intothe separator.

What is claimed is- A cream-separator comprising a cylindricalreceptacle, the cap 2 composed of the oppo sitely-inclined inner andouter walls, the inner Wall being imperforate and united to the outerWall at'the top of the cap and provided with a contracted lower end, andthe outer wall being provided at the upper edges of the receptacle witha perforated lower portion for the escape of gases and having the solidimpert'orate upper portion located between the perforated portion andthe top of the cap, the lower edges of the outer wall being arranged inthe same horizontal plane as the lower contracted end of the inner walland being bent to provide horizontal and vertical ilauges to fit the topof the receptacle, said cap serving
